Barry Mazur and William Stein wish to include the factors of the numerator of the 200th Bernoulli number in their upcoming book, and you can help! This is a large GNFS factorization, but NFS@Home has the ability to sieve it in 2-3 months. Therefore, I am placing 2,1019- on hold for a bit. If you have the memory for it please use the lasievef application help factor B200, and let's complete it as quickly as possible!

If you have sufficient memory, then you can to into NFS@Home preferences on the website, click on Edit NFS@Home preferences, and disable the lasievee application. This will mean that you will only receive the large-memory workunits that are worth more credit.
